VAPORIZER AND CARIBURETER. FOR GAS-ENGINES.

Specification of Letters Patent.

Application filed March 20, 1914. Serial No. 825,988.

To all whom it may concern:

Be it known that I, ROBERT U. WOLFE, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Vaporizers and 'Carbureters for Gas-Engines, of which the following is a specification.

This invention relates to a combined vaporizer and carbureter for gas engines, and has for its object, broadly, to provide a means for conducting lifiuid fuel and water to a diaphragm or vaporization plate together with means for regulating the proportions of these elements, and has reference to the employment of a relief valve arranged to supply air for the vaporizer and carbureter, all to be under control of a single hand-lever so that operation will be convenient.

lVith these objects in view and others to be mentioned hereinafter, the invention presents a novel and useful construction, combination and arrangement of parts as described hercin and claimed and as illus trated in the drawing, it being understood that changes in form, size, proportion and minor details may be made within the scope of the claims withoutdeparting from the spirit of the invention or sacrificing any of its advantages.

In the accompanying drawings Figure 1 is a sectional view on line 1 1 of Fig. 3. Fig. 2 is 'a plan view of the seat of the liquid feed-valve. Fig. 3 is a plan view of the vaporizer and carbureter and parts mounted thereon. Fig. l is an end view of the same, one end of a link being in section. Fig. 5 is a plan view of the bottom of the valve for controlling the intake of liquid fuel. Fig. 6 is a plan view of the bottom of the relief valve. Fig. 7 is a top plan view of the valve shown'in Fi Referring now to the drawing for a more particular description. numeral 7 indicates a vaporizer and (an-bureter provided on its upper side with a liquid feed valve 8. and with a combined intake and relief valve 9, its exit port in its top and near one of its ends being indicated at 10, and it will be understood that port 10 may communicate with the manifold and engine (not shown).

At 11 are indicated small drain-apertures, these preferably being formed in the end of the vaporizerand carbureter opposite to its exit port, near its flat bottom or vaporizing plate 12.

Below and preferably integral With the carbureter is a heating compartment 13 having an intake port l'-.l and an exit port 15, and it will be understood that the exhaust from the engine may pass therethrough in the direction indicated by the large arrows for heating the va orizer and carbureter, the horizontal partition or plate 12 providing a considerable area which may be adequately heated by the exhaust for vaporizing the fuel within the carbureter.

The housing 16 for the liquid feed valve is provided with a stem 17 which extends downwardly near to plate 12. This housing provides a chamber 18 for containing liquid fuel entering from any suitable source of supply through pipe 19. At 20 is indicated a closure-cap traversed by the valvestem 21 which carries the hand-lever-22 for rotating this valve on its seat 23, any suitable packing 24 being employed, the spring for the valve being indicated at 25.

At 26 is indicated a conduit provided in stem 17, having an intake port a adapted to communicate with the port 6 of valve 8 for conducting oil or similar liquid fuel to be discharged Within the vaporizer and carbureter, and stem 17 is provided with a conduit 27 having a bore of less diameter than the bore of conduit Q6 and having an intake port 0 adapted to communicate with the port (1 of valve 8 for conducting water from supply pipe 28 to the vaporizer'and carbureter, the intake port from pipe 28 being indicated at e.

By reference to Fi g. 1, it will be seen that port (Z of valve 8 does not communicate with chamber 18, also that ports 6 and d of said valve are of elongated form, one ofthe ends 01 of each port being convergent. This is a desired construction for the reason that when valve 8 is rotated by an operator by use of lever 22. the convergent ends of ports 7) and (Z may be in communication with the respective conduits Q6 and 27 to limit the supply of liquid which may pass therethrough; however, by use of the hand lever PatentedFeb.9,1915.

the valve may be rotated somewhat further to permit a reater supply of liquid to pass through the valve, and this construction provides one of the means for' controlling the quantity of liquid fuel and water to be supplied to the vaporizer and carbureter.

Valve 9 is for the'purpose of permitting or preventing the passage of airto the vaporizer and carbureter, except the limited amount of air which may pass through apertures 1-1 and'k, and it is under control ot the hand lever.' It is provided with ports 28 and 29 adapted to register respectively with ports 30 and 31 of the vaporizer and carbureter, ,ThlS valve is provided, centrally thereof, with a barrel 32withinwhich is mounted the detent" or screw 33 to provide a bearing for one end of the spring '34, and since the screw is threaded in the top of r {valve 9 to be pressed upon its seat with a the-carbureter, it may be adiusted'to cause i v force suflicient for all practical purposes,

and operates as a relief valve if the pressure of carburetedsairin the carbureter at any time greatly. exceeds the force of the spring. In orderithat valve 9 may be rotated coincidentlywith valve 8, it is provided with the angular arm 35 provided 1 with the slot 36. The valve stem 21 is provided with the transverse arm .37

7 At 38 and 39 are indicated a'pair of links connected at their inner ends by means of the knuckle joint 40, their respective outer ends being pivotally mounted upon arms 35 and 37. v

In operation, by reason of the provision of the knuckle joint, the relief'valve may move upwardly by force of the carbureted air within the vaporizer and carbureter,

against the force of spring 3 1, and the rotatable-movements of the valve stem 21 will veffect corresponding movements of valve 9, to cause or prevent a registration of the ports of; valve 9 with the ports of the vaporiz'er and carbureter.-

'7 Atellfis indicated a keeper disposed in sloti36 for a mountingon arm 35, and b means of this keeper the outer end of lin 38 may be adjustedlongitudinally of said armlwiththe result that one of the rotatable movements of the valve stem 21 may cause the valve9 to rotate in a degree suflicient to cause a closure of the intake ports 30 and 31 of the vaporizer and carbureter, or this adjustment may be such that the intake ports will be partly closed by said rotatable move- 7 ment of valve stem 21.

At 12 is indicated a vertical prop extend; ing between the diaphragm or plate 12 and the bottom it of the heating compartment, its'aperture lc opening upon the vaporizer and carbureter substantially at-the middle of plate 12, and providing an additional drain or waste pipe for the vaporizer and carbureter extending through the bottom of the heating compartment 13, said prop also operating, to sustain the stresses directed outwardly of plate 12, incident to the use of the vaporizer and carbureten- Port 1) of valve 8 is preferably formed with a convergent terminal 2, and it will be understood that this valve may be disposed with its terminal 2 in communication with port a, the portorraceway d not being in communication with port 0, this construction being for the purpose of supplying the vaporizer and carbureter with gasolene when the water supply is entirely cut off.

As thus described, oiland Water or other i ingredients, together with air may besupplied to the vaporizer and carbureter in any desired proportions. The ingredients which pass through conduits 26 and 27 are kept separated until they reach, substantially, the vaporizing plate; the exhaust from the engine will cause plate 12 to attain a great heat. The suction from the engine will cause air to be drawn through ports 30 and 31 and will cause the vaporized oil, water bureter, a iousing provided ,with a plurality of lntake ports and having a plurality of conduits communicating with the vapor-- izer and carbureter, a first valve provided with a plurality of ports adapted to have a rotatable movement while seated in said housing to dispose each of its ports in communication with one of the intake ports of said housing and with one of said conduits, and a second valve resiliently mounted on with the atmosphere and rotatable by the movement of the first valve to dispose its the vaporizer and carbureter and provided with a plurality of ports communicating ports in communicationwith the ports of said vaporizer and carbureter.
